What is the solution? pls help
loris [4]

Answer:

Solve by substitution

[y=5/2x-4]

[y= -x+3]

Substitute y = -x +3

[-x+3=5/2x-4]

Isolate x for -x+3=5/2x-4: x=2

For y = -x+3

Substitute x = 2

y= -2+3

Simplify

y=1

The solutions to the system of equations are:

y=1 x=2

For a recent year, 38 more Democrats than Republicans represented a country. If the total number of representatives of the count
Fantom [35]

Second question isn't well formatted

Answer:

Number of republicans = 207

Number of democrats = 245

Step-by-step explanation:

Let :

Number of republicans = x

Number of democrats = x + 38

Total number of representatives from the two parties = 452

Tge number of representatives from each party can be calculated thus ;

Number of democrats + number of republicans = total number of representatives

(x + 38) + x = 452

x + 38 + x = 452

2x = 452 - 38

2x = 414

x = 414 / 2

x = 207

Number of republicans = 207

Number of democrats = 207 + 38 = 245

Compare the functions shown below:
emmasim [6.3K]
The intersection with the y axis occurs when x = 0.
 We have then:
 
 For f (x):
 
f (0) = -3 (0) - 5

f (0) = 0 - 5

f (0) = - 5

 For g (x):
 
We can observe in the graph that when x = 0, the value of the function cuts to the y axis in y = -3

 For h (x):
 
h (0) = 2cos (2 (0) -\pi) +4

h (0) = 2cos (0-\pi) +4

h (0) = 2cos (-\pi) +4
 h (0) = 2 (-1) +4

h (0) = -2 + 4

h (0) = 2

 Therefore, the graph with the intersection with the largest y axis is h (x)

 Answer:
 
the greatest y-intercept is for:
